As this is the beginning of the 40 days of the denominational Christian period of Lent, it is worthwhile demonstrating what Kepler's Lenten Pretzel really represents.

"Copernicus, by attributing a single annual motion to the Earth, entirely rids the planets of these extremely intricate coils, leading the individual planets into their respective orbits, quite bare and very nearly circular. In the period of time shown
in the diagram, Mars traverses one and the same orbit as many times as the 'garlands' you see looped towards the centre, with one extra, making nine times, while at the same time, the Earth repeats its circle sixteen times " Kepler Astronomia Nova 1609
Mathematicians, following the lead of Sir Isaac Newton, still imagine the diagram is geocentric despite the description of Kepler, which refers the direct/retrograde motions of Mars against the background constellations rather than a stationary and
central Earth as the following diagram has it-

This is to help theorists understand what their absolute/relative space and motion represent within the scheme of Newton, where the Earth at the centre was meant to represent relative space and motion while the Sun at the centre is meant to represent
absolute space and motion-
"For to the Earth planetary motions sometimes appear direct, sometimes stationary, nay, and sometimes retrograde. But from the Sun, they are
always seen direct..." Newton
From my recent excursion to an external forum, contributors were terrified of actual astronomical history and especially the nuances of technical descriptions. It shouldn't be the case because mathematicians have found their true calling in writing
computer code rather than messing around with solar system or Universal research using flawed precepts.
There will always be those who have no problem dining out of contrived explanations, and they are welcome to it; however, there will also be those who cannot yet see that there is a more productive and creative use of observations ahead.
